Working with an XML PHP parser

You can use an XML parser to work with the XML data in an XML file. While writing the code to work with the XML parser and the XML data, you have to think of three major steps in the code.

The first thing is you need some function to handle the starting tags that are encountered in the XML file and another function to handle the actual data and a third one to handle the end tags encountered while navigating the XML file.

Now you have to create a parser using the command 'xml_parser_create();'. To handle the starting tags and the end tags you can use the 'xml_set_element_handler();' and for handling the data you can use

'xml_set_character_data_handler();'. Both these take the XML parser as the first argument. Now open the XML files, read it, and parse it. After you have completed your task you have to free the memory that the parser has taken and then close the XML file you have used.
